Fig. 10 is a tate,rwhich disks are united by bars L2, in roo which bearings are formed for a series of shafts M, said shafts being provided alternately at opposite ends with the worin-wheels N, engaging worms N' on two shafts N2, arranged parallel with said bars L2 and having their ends mounted to rotate in the disks L L'. vEach shaft N2 carries at one end a pinion O, which engages the circular rack O', having a hub P', mounted loosely on the sleeve l), 011e end of which is fixed centrally in the disk L'. On the hub P' a worm-wheel P2 is fixed, which engages a worm Q on a horizontal shaft Q', arranged transversely to the length of the machine-frame and suitably journaled in bearings on the top of said machine-frame, which shaft Q' carries at its end a bevel eog-whecl Q2, engaging the bevel cog-wheel Q3, which is fixed on the same shaft Q4 with a cog-wheel R, the shaft Q4 of said united bevel cog-wheels Q3 and R being mounted in a bracket A2 on the side of the machine-frame. The cog-wheel R engages a cog-wheel R', mounted to turn on an L" shaped arm R2, that is mounted to swing on the shaft Q4 of the bevel cog-wheel Q3 and cog-wheel R, which L-shaped arm has a segmental slot R3, through which a bolt R4 passes from the bracket A2. The cog-wheel R' engages a pinion S on the end of the shaft4 S' of a tapering drum S2, over which a driving-belt S3 passes, that also passes over a tapering drum S4, fixed on the counter-shaft C2. The pinion S is interchangeable and can be replaced by a smaller or larger wheel, for a purpose that will be set forth hereinafter, and to permit of interchanging said cog-wheel the arm R2, on which the cog-wheel R' is mounted is made adjustable, so as to adapt it for the various sizes of wheels.

Between the bars L2 a soft-rubber roller M' is mounted on each short transverse shaft M, the rim of each roller having a concave annular groove. As said rollers must be made interchangeable, so as to adapt the machine for tubes of various diameters, the same are constructed as shown in Figs. 8 to 11. The shaft M is provided with two transverse slots no', through which pins m2 are passed, the ends of which rest in the notches fn.' of the central necks n2 of the end plates a3, which are mounted loosely upon the shafts M and rest against the side faces of the rollers h Screws 0 are screwed into threaded apertures extending from the ends of the shafts M to the slots m', the inner ends of said screws 0 bearin g against the transverse pins m2. Said screws press the transverse pins m2 against the necks 71,2 of the disks n3 and thus press said disks n2 against the sides of the rubber rollers M', thereby holding said rollers in the proper place 011 the shafts M.

lVhenever a roller is to be removed, the screws o are loosened, so as to permit of removing the pins m2, and then the end disks n3 and the roller M' are removed and a new roller is placed upon the shaft with the end vthe mandrel.

disks n3, the pins m2 are replaced, and the screws 0 drawn up so as to press said pins m2 against the end disks and said disks against the sides of the rubber roller. In this way the machine can easily be adjustable for tubes of: various diameters. Said rollers M' must be inter-changed to suit the various sizes of the tubes, and to facilitate this interehangin g the shafts of the rollers are held in place by detachable bearing-blocks T, (see Fi 1,) which are held in place by bow-springs T', fastened by screws T2 to the bars L2, each bow-spring resting on two adjacent bearingblocks. The mandrel D' passes between the two sets of rollers M'. A belt-pulley W is fixed on the sleeve P, and over the same a belt NV' passes, that also passes over a pulley W2 on the counter-shaft C2.

The operation is as follows: The paper strip a' is drawn from the reel upon the mandrel and is wound upon the same spirally by hand until the coils of the spiral have been passed through the rotating sleeve G, the belt and pulleys of which are so arranged that the speed of said sleeve is different from that of This rotating sleeve holds the paper coil snugly on the mandrel and pre vents 4unwinding of the same. Immediately beyond the sleeve G the two paper strips b D' are wound upon the core on the mandrel, the strip b', which is provided with paste on both sides, being wound on first, and the strip b is wound directly upon the strip 'b'. The completed tube now passes on the mandrel in between the rubber feed-rollers M' and the rotating frame formed by the disks L L' and the bars L2, and thereby the several layers of paper forming the tube are pressed together by the grooved rubber feed-rollers M' and at the same time the tube is drawn forward. The speed of rotation of said rotating frame on its longitudinal axis must be different from the speed of rotation of the mandrel and its pulley, so as to form the spirals. As said frame rotates, the pinions O on the shafts N2 are rotated as they are engaged with the circular rack O'. The said circular rack rotated around the cylinder I by means of the worm-wheels and gearing described and the belt S2 from the shaft C2. Accordingly said circular rack O' is rotated with greater or less speed, or in the same direction or the reverse direction of said pinions O, the speed of rotation of the shafts N2, and consequently the speed of rotation of the shafts M of the rollers M', varies. The paper strips are not always of the saine width and thickness, and in order to cause the edges of said paper strips to lie snugly and closely against each other, so as to form close and tight joints, it is necessary to regulate and govern the speed of rotation of the feed-rollers M' accordingly. The operator of the machine can easily accomplish this by varying the speed of' rotatation of the circular rack O' around the cylinder P. The said feed-rollers M' press the IOO IOS

IIO

layers of paper firmly against each other and firmly against the mandrel D', which, as shown in dotted lines in Fig. 3, passes in between the two layers or sets of rollers M. The mandrel D rotates in the same direction as the frame formed by the two disks L L and the bars L2 uniting them, but, as stated before, the speed of rotation of said frame is different from the speed of rotation of the mandrel. The rubber feed-rollers M do not only press the strips of paper against each other and against the mandrel, but at the same time theymove the tube forward in the direction of its length by drawing it off the mandrehwhich travels, as has been previously stated, at a rotary speed different from the speed of rotation of the frame formed by the disks L L and the bars L2 uniting them, both said frame and the mandrel rotating on the same longitudinal aXis. As the mandrel runs in between the rubber feed-rollers it permits of exerting considerable pressure by said rollers on the tube without crushing the latter, and thus a friction can be obtained between the feed-rollers and the tube to draw the tube off the mandrel and move it in the direction -of its vlength uniformly.

The variation of speed that can be accomplished by shifting the belt S3 on the two pulleys S2 and S4L has certain limitations, and sometimes it is necessary to adjust the machine beyond these limitations, and in that case the pinion S is removed from the shaft S and is replaced by a wheel of greater or less diameter.
